Calathea leaves are used in the tropics (mostly Brazil) for handicraft and food wrapping. Because of the diversity of the leaf shapes, baskets are weaved with the lanceolate leaves, and food is wrapped with the wider leaves. The colorful leaf markings of most Calatheas make them economically important as houseplants, and their popularity has been growing. The Calathea veitchiana ‘Medallion’ (Medallion calathea), Calathea lancifolia (Rattlesnake calathea), and the Calathea ornata (Pinstripe calathea), are some of the most popular species.
Thrives in medium to bright indirect light, but can tolerate low indirect light.
Water every 1-2 weeks and adjust frequency depending on light levels provided. Allow soil to half-dry out before watering. Soil should be almost dry about 2” down. <
Does better in higher humidity if possible.
